CLINTON W. RUSSELL, OF DETROIT, MICHIGAN.

DUMP-(JAB.

Specification of Letters Patent.

Patented April 13, 1909.

Application filed March 3, 1908. Senial No. 418,986.

To all whom "it may concern Be it known that I, CLIN'roN W. llUssELL, a citizen of the United States of Jhnerica, residing at Detroit, in the county of Vl' avnc and State of hflichigan, have invented certain new and useful Improvements in Dump- (Jars, of which the following is a specification, reference being had therein to the accompanying drawings. Y

The invention relates to railway dumping cars, and consists in the novel construction of mechanism for operating the sides of the car, as more fully hereinafter set forth.

In the drawingsFigure 1 is a perspective view of the car in normal position; Fig. 2 is a similar view illustrating the operation of dumping; and Fig.3 is a diagrammatic view showingthe operation of the mechanism.

*A is a railway dump car, of any suitable construction but which, as shown, is provided with a frame 13 having arranged centrally thereof the pivot bearings C for supporting the box body.

D are rockable supports for engaging the bottom of the body upon opposrte sides of the central pivotal support, and which may be adjusted to permit the tilting of the body in dumping the load.

To permit the discharge of the load when the body is tilted the sides E of the body are removable and mechanism is provided for automatically operating the same. This mechanism comprises a system of links and levers so arranged that as one edge of the body is lowered, the side member thereof is raised and moved into a position which is substantially parallel to the bottom of the body when completely tilted.

In detail F is a link which is pivotally attached at one end to the end of the side or door E near the bottom edge thereof, the

opposite end of said link being pivotally attached at G. to the center of theend H of the body and near the upper edge thereof.

I is a strut rod pivotally attached to the link F intermediate its ends and extending downward, the lower end being attached to a link J. This link is pivotally attached at its inner end K to the frame B, while the outer end is adapted to rest upon the bearing L on said frame.

M is a second link'pivotally attached to the end of the side or door E'and near the upper edge thereof. This link is pivotally attached to a cooperating link member which, as shown, is formed by a member N secured to the strut rod 1 and projecting laterally therefrom. The pivotal conncctimi between the members Id and N. so located that in the closed position of the door E this pivot is in line with the pivots a and b .which respectively connect the rod I with the link I and the link M with the doorll. Thus the members M and N together form a. pair of toggles, which are straightened out in the closed position of the door so to form a rigid link.

With the construction as described whenever the car body is tilted in either direction the strut rod I upon the side of the body which is lowered will hold the link F from lowering with the body. At the same time, the strut rod I is free to swing so as not to interfere with the' movement of the inner pivoted end G of the link F, the result being that the door is swung outward and u )ward as the body moves downward. The c ha-nge in angularity of the link F and strut rod I will cause a partial folding of the toggle members M and N, which will shorten the distance between the pivots a and b, and this will result in throwing inward and downward the upper edge of the door E until the latter is arranged in parallelism with the bottom of the body. During the movements just described, the strut rod I on theupwardly moving side of the carwill be raised, but this movement will be permitted by the upward swinging of the link J without producing any alteration in the relative positions of the links F and the members M and N which are connected to the door on that side. The

freedom for upward movement of the strutrod I may also be employed for raising the door at any time without tilting the body.

What I claim asmy invention is:

1. The combination with a car body, of a removable door or side thereof, a pair of pivotal links for connecting the. end of said door to the end of the body, one of said links being formed of a pair of toggle levers which are straightened in the closed position of the door and are foldable as the door opens, and both links forming rigid tie for resisting lateral stresses on the do r when in closed position.

2. The combination with a car body, of a door forming one side thereof, a pair of pivotal links for connecting the end of said door with he end of saidbody, one of said links being Iormed of foldable sections or toggles, said toggles being straightened in the closed position of the door and being ivotallyv connected at one end to the other ink.

3. The combination with a car body, of a door forming one side thereof, a pivotal link extending between the end of said door near the lower edge thereof and the end of the body near the center of the u per edge there- Of, and a foldable sectional ink connecting the end of the door near the u per edge thereof, and a point intermediate t 1e ends of the first mentioned link, said foldable link being straightened in the closed position of the door.

4, The combination with a tilting car body, of a door at one side thereof, a pivotal link connected to the end of the door near thelower edge thereof and inclining upward toward the center of the end of the body to which it is attached, a rockable strut connected. to said link and having a fixed bearing for its lower end and a foldable sectional link connecting tlie end of said door near theu per edge thereof with said first mentioned ink, one of said sections of said foldable link being rigid with said strut.

5. The combination with a tilting car body, of a door at one side thereof, a pivotal link connected to the end of said door near the lower edge thereof and inclining upward therefrom to the pivotal connection with the end of the body, a rockable strut having a fixed supporting bearing for its lower end and pivotally connected to said link intermediate the ends of the latter, a lateral extension rigid with said-strut, and alink-pivotally connected to said lateral extension and the end of said door near the upper edge thereof, for the purpose described.

6. The comblnation with a tilting car body, of a door at one side thereof, apivotal link connected to the end of said door near the lower edge thereof and extending inward to its point of pivotal connection with the end of said body, a rockable strut having a fixed bearing for its lower end and pivotally connected to said link intermediate the ends of the latter, a foldable link extending between said strut and the end of said door near the upper edge thereof, the said parts being proportioned to move said door into substantial arallelism with the bottom of said body w en the latter is' tilted.

In testimony whereof I aflix my signature in presence of two witnesses.
